Abstract
The invention provides a hinging joint structure of a large-span prestressed concrete framed girder. The hinging joint structure comprises a framed girder (1) and a framed column (2) which are integrally connected to form a prestressed concrete frame structure. The hinging joint structure is characterized in that an inner side isolating layer (3) and an outer side isolating layer (4) are respectively arranged at the inner side and the outer side of a plane in which the bottom surface of the framed girder (1) is intersected with the top surface of the framed column (2); the framed girder (1) and the framed column (2) are connected through a reinforced concrete core column (5); a reinforced concrete girder pad (6) is arranged at one inner side of the framed girder (1), at the inner side plate isolating layer (3). According to the hinging joint structure, a side column of the large-span prestressed concrete frame of a roof is structured into a single hinging form, thus the bending moment transmitted by the large-span prestressed concrete framed girder can be released, the framed column at the side can be kept in a small-eccentric pressing state, and as a result, the quantity of reinforcement and the section dimension can be reduced, the bearing performance of the frame structure can be improved, and the large-space design requirement of a building is met.
